"So, this was mom's place huh?" Ryūko said as she and her sister Satsuki stood outside of Ragyō Kiryūin's mansion. With Ryūko wearing a dark biker jacket with a deep red shirt, with dark blue shorts and black boots with white thick socks coming out of the boots. While Satsuki wore a light blue dress with a white coat over it with dark tights on and blue shoes on. 

"Yes, even though me and mother had our own mansion which we shared, this was her private one, even I have never been inside..." Satsuki remarked as Ryūko looked at the place questionably. 

"Yeah, I feel like there may be some Life Fiber traces inside for sure..." she as Satsuki glanced at her. 

"Can you face it without Senketsu at your side?" she questioned as Ryūko smirked at her sister. 

"And you without Junketsu?" she questioned as Satsuki scuffed. 

"I only needed it to match your hax powers, now come on..." Satsuki said as the sisters made their way inside, quickly searching the massive mansion over to find nothing of note or of any value but tons of discarded old clothing and designs from Ragyō's earlier days. 

"Maybe there was nothing after all?" Ryūko muttered as Satsuki shook her head. 

"No, there is one place, her bedroom," she said grossing out Ryūko. 

"Eww, I do not want to see mom's bedroom!" 

"Suck it up..." Satsuki said as both sisters made their way in, upon examining it, the room was normal to the naked eye. 

"Huh? See! Nothing here, let’s go!" Ryūko said as Satsuki stopped her. 

"Wait, what’s that?" Satsuki said pointing to a photo frame which they soon walked up to. Upon looking at it, the picture frame showed a picture of their mother and father together, looking very happy. 

"Tsk! Why is something like this here?" Ryūko muttered while attempting to pull the frame away, however it merely moved forward and downward, which slid away the nearby bed to reveal a hidden staircase going underground. 

"Looks like mother did have some perversions...." Satsuki noted. 

"Tsk, she was a creepy one, incestuous pervert..." Ryūko stated as both sister's glanced at one another, nodding in agreement to go down together as they soon descended the staircase, leading to a dark life fiber room. 

--------

"What in the?" both sisters remarked while flipping on the light, the light revealing a room full of adult like clothing consisting of dominating BDSM latex and leather gear of all shapes and sizes. 

"Ngn..." Satsuki simply looked on disgusted as Ryūko gripped her hands. 

"Can't believe she was into this stuff..." Ryūko stated as Satsuki smirked. 

"Says the one who wore a school uniform that transformed into a very revealing outfit," she teased making Ryūko blushed slight. 

"Don't remind me! Anyways, let’s see if this clothing is alive or not..." she said as both sisters walked forward and began examining the outfits. What they saw left them cringing and squirming a bit, before Ryūko took notice of a wall full of all kinds of gags, bindings and torment items. 

"I never thought mother be into this kind of stuff," Satsuki said as Ryūko had shivers now. 

"You know what? Forget this place, let’s just light it on fire and be done with it!" she said with Satsuki nodding, the moment she nodded though a nearby leather hood suddenly sprung to life, soon wrapping around Satsuki's head. 

"MRPMR?!" Satsuki cried out while stumbling backwards towards some more awaiting bindings as Ryūko heard the muffled cry and turned around. 

"Satsuki? Satsuki!" Ryūko cried out trying to hurry towards her, though the bindings behind her suddenly lashed out, wrapping around her ankles and bringing her to the floor. "Gaaah!" Ryūko cried out painfully as she glared backwards at what gripped her legs. Upon looking back, she saw the life fiber latex was pulling her backwards to where more awaited to bind her. "Damn you! Let me go! Release me!" Ryūko cried out as she instinctively reached for her scissor blade only to feel air which it reminded her they were adrift in space. "Craaaaap!" Ryūko cried out as she was sharply tugged towards the latex. 

"Rrmhnnh! Rmmmhnnnm!" Satsuki cried out her sister’s name as she pulled at the hood that covered her face, the only opening on it was for her nose to breath with as she kept being pulled backwards by it. Which before long more leather bonds jumped out at her, starting to restrain her body while latex did the same with Ryūko. 

The bindings that lined the wall also now jumped out and began to bind the sisters, ensuring their limbs remain totally bound thanks to the driving force of the Life Fibers that made up them. 

For both sisters’ bindings, thumb cuffs bound their thumbs together, which was reinforced with wrist cuffs and then arm cuffs with short chains to hold their arms tightly together. Over that they got their own version of Monogloves, which thick straps wrapped over that and above and below their breasts to pin their arms behind their backsides, not allowing a single muscle movement. 

Once their binding material reached their feet, the material formed BDSM boots with extreme four-inch heels, which Satsuki instantly began to feel as their feet were placed in extreme discomfort. Ankles cuffs were used to keep them pinned with leg covers over that with more wrapping thick straps to ensure their locked limbs. 

The material formed thickly knotted rope like form between their crotches, digging deeply to make both women gasp and moan out, which as their mouths remained open, a very large dark ball gag filled their mouths which the material over Satsuki's face opened up for a moment to receive it before closing back up which a latex hood soon appearing over Ryūko's head to seal her up. As the hoods began to block out all their senses, they could make out the bed door closing up, leaving them trap in the hellish pit alone with the attacking Life Fibers. 

"NNRNRRMM!" they both cried out, Ryūko now fully bound in latex while Satsuki was bound in all leather. Despite their efforts in getting free, they both wormed and moaned out, despite blushing under the material as the crotch rope made shocks of pleasure race through their bodies as it dug further into their crotches. 

"Ngng hrhrm mrrhpmmm!" they both grunted out, no longer able to hear the cries of each other as they soon both gasped, feeling the outfits they had worn into the mansion being devoured by their bindings, slowly the cloth fibers eaten up till they were completely nude. "Nrnrmrmmm!" they groaned out but soon felt strange as their binding fibers seem to spew something back out, a cold and shivering liquid that coated their bodies, soon being promptly absorbed by their skins. 

"Nrnrmmm?" they both moaned out as their bodies began to tingle like mad and then hot which soon it felt like their binding material was a lot more pleasurable and turned the crotch rope into a stronger feeling. 

"MMMMMMM!" Ryūko cried out, confused by it all while Satsuki knew what it was, it could only be an aphrodisiac of some sorts. 

"Mmmmmphphmmmm!" Satsuki let out a shuddering moan as she began to feel too good from it all, which both sisters began to moan and squirm like crazy. Before long some special electro stim pads were being led towards their wiggling bodies, which for Satsuki she still hopped in place on her long heel shoes.

"MMMMMRRRHH!" both females cried out, the latex and leather that bound them was rubbing their bodies in pleasuring ways. The sweat rolling down their bodies added to the effect along with the crotch rope, though they both twitched upon feeling the electro stim pads attach themselves all over their bodies, mostly around their breasts and crotch areas. 

"Mphpmm?" they both moaned confused before a strong static began to course through their bodies. "MRMRM!" they both cried out twitching madly, Ryūko jumping up as Satsuki went hopping backwards while squirming madly to keep her balance. With another shock Satsuki was sent falling to the floor, joining Ryūko in her squirming on the floor like a worm. 

"Mrprhprm! Mrmrmrm! Mrmrhrhrmrm! MMMMMM!" both sisters cried out through their hoods, the pleasure and shock driving them mad. Despite their increasing anger, they could only resist their torments for so long as their minds began to go blank and the shock and pleasure began to take over any thoughts they had. 

This did take a few hours until the life fibers in the latex and leather began to feel the sister's wills breaking. Which their long moans and drooling mouths giving a good indication they could move onto the next process as the electro stim pads pulled itself away. 

As to torment them further, both sisters received a tight leather corset, the material pulling itself tightly over their middle chest area. It kept pulling and squeezing till both females screamed into their gags from how tightly their mid bodies were being hugged and squeezed, soon giving them an hourglass figure shape. 

"Mmmphpmmmm..." both whined out weakly, panting like mad through their nose as it felt like Ira Gamagōri was crushing the spirit out of their bodies. 

Left delirious and weaken, both could do little as their bodies were forced to curl up and soon jump upwards, landing painfully on their heel feet. 

“Mmphpmmm!” both females letting out a cry as Ryūko simply could not stand while Satsuki had some endurance to it as both hopped towards each other which the pain seem to snap them back to some sort of senses.  

"Mphpmm?" the sisters grunted, confused as to where they were being led, which each hop made them cry out as the crotch rope tug deeply into their crotch folds. Before long both were standing in front of each other with Satsuki hopping in place, slowly turning herself around and was forced to bend over, the coreset painfully pulling at her chest more as her ass was up for display, which a long dildo began to form in front of Ryūko's crotch, which was double sided and working its way into Ryūko’s crotch at the sametime. 

"MMMM!" Ryūko cried out as the latex was plunging itself deeply into her pussy, the pleasure she felt made her go lightheaded for a moment, as she came back around, she realized she was thrusting into something warm and a bit flabby. "Mphpmmm?" she moaned confused, unable to hear the cries of Satsuki as the dildo dove deeply into her ass, the leather moving out of the way enough for her to be penetrated deeply. 

"Mgmgm! Mgmgmg! Mgmgmg! Mgmgm!" Satsuki cried out as the thrusting happened over and over untill she felt something wet penetrate her, confused to what it was as the dildo was now channeling Ryūko's cum, the thrusting had finally made her orgasm which her cum went trailing into Satsuki's ass. 

“MMMPHMMM!” Ryūko was currently crying out, feeling herself explode into the latex that pleasured her, and felt a soothing relief over her body. 

The latex soon retracted itself, Ryūko now crying out as she was forced to hop around, Satsuki now hopping behind her as a leather made its own dildo and now entered Ryūko from behind and began to return the favor. 

"Mrmrm! Mrmrmr! Mrmrmr! MMMMMMM!" Ryūko screamed out, getting it a bit rougher with the leather strap on. Unlike Ryūko, Satsuki couldn't hold it back very well and quickly orgasm, her cum sliding into Ryūko's ass confusing her to what it could be. 

“MMMMMMPHHHH!” Satsuki screamed from her orgasm, truly overcome by a first blissful experience. 

Ryūko couldn't think on it much as she was soon hopped back around, forced to her knees where she began to deep throat Satsuki's strapon, the cum still coating it from the butt fucking as Ryūko got to unknowingly taste her sister. 

"MMGMGNGNM!" Ryūko cried out, still unaware what the liquid was or what could be jamming so deeply into her mouth. The motions kept her thinking blank though, as she took it all the way into her mouth, Satsuki's crotch slapping against her mouth before Satsuki was once more forced to orgasm, the cum washing down Ryūko's throat. "NGNGN!" she gagged and coughed on it, before long their roles were reversed, Satsuki now taking Ryūko's latex strapon into her mouth. 

"MMMMMMMMMMM!" she cried out, trying to bite down on it with no luck as the latex dildo thrust all the way into the back of her throat, making her gag and sputter as the crotch rope reacted to her biting, making her grunt and moan hard. Ryūko couldn't take much of the vibrations of Satsuki's mouth being fucked, soon making her orgasm just as hard into her mouth, her cum splashing down her throat. 

"Mmmmmm!" Satsuki groaned out as both sisters fell to the floor, their bodies lining up rather perfectly as the latex and leather around their crotches began to form outward and meet up, soon doubling back and forming a double-sided dildo between the sisters. 

"Mrhmmm?" both groaned, confused what was going to happen as their bodies began to thrust against one another. "MRMRMR!" they both cried out, the Life Fiber dildo fucking them both, before long though the fibers stopped having to move their bodies, the sisters moving their own bodies to the thrusting motion. 

"Mrmrmr mrmr hrhrm mrmrmrm!" Ryūko moaned out seemingly thrusting out harder into Satsuki. 

"Mmmphpmmmmmm!" Satsuki moaned out, seemingly easing into the thrusting, enjoying taking it more than giving it but still kept up the thrust motions only to be thrust harder back. 

"Mrmrmrm! Mrmrmr! Hrhrm! Mmmmmmm!" they both cried out as they panted and gasped harder before orgasming in unison. "MMMMMMM!" they both cried out, despite the orgasm that shudder and shook their bodies, they kept at it, their bodies moving in tandem with one another, making the other orgasm over and over. 

Eventually the hoods receded, just enough for the other sister to see what they were thrusting against, soon realizing they were heavily fucking each other, making the other happily orgasm. 

"Mmphpmmm..." they both moaned sensually, leaning in for a gagged kiss as the hoods soon once more bound their heads. As they did, a heavy sleep sack began to wrap around them both, trapping them in a very tight pod embrace as their bodies now hugged each other, the latex and leather bonding with one another to form one tight cocoon for the sisters. "Mphpmmm..." they gasped out, still moving their hips and making the other cum strongly. 

As the sleep sack zipped itself up, it seem to be the eternal end for the sisters.

"Ryūko! Satsuki?" Mako called out entering the mansion and looking for her best friends clad in her iconic school uniform. "Did you find any naughty Life Fibers?" she asked though got no reply back as she searched the mansion over in a rapid comedic fashion. 

"Huh? Did they leave?" she wondered before finding the main bedroom. "Whoa! This is just like that time we earned the high life privilege! I do miss that bed, well.... no time like the present!" she said kicking off her shoes and flung herself upwards to land on the bed. 

However, her shoes came down first, knocking over the picture frame, which moved the bed before Mako could land on it which sent her rolling down the stairs in a cartoon like spin. 

"Whoa!" she cried out landing hard on the sleep sack, her force of impact separating the latex and leather from the sisters, leaving them nude, sweat covered and panting heavily between Mako. 

"Huh? Ryūko! Satsuki! What on earth happened to you both?" she asked the breathless sisters as the Life Fibers were angered by this, but soon sensed something from Mako. Before long the fibers began to snake under Mako's outfit, which would soon grant her a powered dominatrix outfit to further torment the sisters who were soon pulled from the mansion, with them all believing the fibers were gone for good upon finding them nowhere in the hellish basement but unaware they were hiding for a better pleasuring time.
